Does anyone know of a heavy duty or otherwise well made long tube header that would support the sas systems found in other markets? I am looking at the gtspec with "egr" on maperf but i really would prefer a long runner tuned length setup.

Thanks!

 

I have seen many gt spec manifolds crack lol.. I would give JM Fabrications a call, I am sure they would have no problem making one for you, and they do top quality work.

 

Gotcha. I am def looking for sch quality. Had gtspec on my sti swap and it cracked. I have a jmf intercooler, wasn't impressed witg the dent in the core, but otherwise great fabrication.

 

I would look no further than the MAP tubular exhaust manifold, my friend.
